Best Plumbing in Plano, TX — 24 Vetted Contractors

Yes. The City of Plano requires a permit for water heater replacements. Your licensed plumber should pull this permit before starting work — it's typically included in their quote or listed as a separate line item ($50–$100 range). An inspection will follow to verify proper installation, venting, and seismic strapping. If a plumber tells you a permit isn't required for a water heater swap in Plano, find someone else. Contact Plano Development Services at 972-941-7151 to verify current requirements.

Polybutylene pipe is gray, flexible plastic, typically found at the water meter, under sinks, and at fixture connections. It's often labeled 'PB2110' on the pipe itself. Homes built in Plano between roughly 1978 and 1995 are the most likely candidates. If you're unsure, a licensed plumber can do a quick visual inspection — this usually takes 15–20 minutes and some plumbers will do it at no charge during a service call. If you have PB pipe, get a repipe assessment sooner rather than later.

A slab leak is a break or pinhole in a supply or drain line that runs through or under your concrete slab foundation. They're more common in Plano than in many other markets because of the expansive clay soil that shifts seasonally, stressing embedded pipes. Warning signs include: unexplained spikes in your water bill, warm or wet spots on floors, the sound of running water when everything is off, or foundation cracks appearing suddenly. Detection typically costs $300–$600; repair costs range from $1,500 for a simple reroute to $15,000+ for tunneling.

Go to tsbpe.texas.gov and use the license lookup tool. You can search by the plumber's name or license number. A valid Texas plumbing license will show as active, list the license type (Master or Journeyman), and show the expiration date. Per the Texas State Board of Plumbing Examiners, all compensated plumbing work in Texas requires a valid TSBPE license. This check takes under a minute and is the single most important verification step before hiring.

Yes, Plano's water is moderately hard — typically in the 150–250 mg/L range as calcium carbonate, depending on the season and which North Texas Municipal Water District source blend is in use. This accelerates scale buildup inside water heater tanks (reducing efficiency and shortening lifespan), clogs aerators and showerheads, and can affect appliances like dishwashers and ice makers. A whole-house water softener runs $800–$2,500 installed in the DFW market. At minimum, flush your water heater annually to remove sediment.

First, locate your main water shutoff — in most Plano homes it's near the water meter at the street or at the point where the main line enters the house. Shut it off immediately to stop water damage. Then call a licensed 24-hour emergency plumber. Expect emergency/after-hours rates to be 1.5x–2x standard rates — this is normal and disclosed upfront by reputable contractors. Do not wait until morning if water is actively flowing; even a few hours of water intrusion can cause mold and structural damage that costs far more than the after-hours premium.

Yes. Plano follows a tiered watering schedule ordinance, and during drought conditions the city can implement Stage 1–4 restrictions that limit irrigation days and times. As of 2025, Plano's standard schedule allows watering twice per week based on address. Irrigation system repairs and backflow preventer testing should be scheduled with these restrictions in mind. Plano also requires annual backflow preventer testing by a licensed backflow assembly tester — check plano.gov/water for current stage status and schedule requirements.

A full repipe of a typical 2,000–2,500 sq ft Plano home generally takes 2–4 days for a crew of two to three plumbers. Water will be shut off during working hours each day but restored overnight in most cases. Drywall patching (to access pipes in walls) is sometimes included and sometimes a separate contractor — clarify this upfront. You typically don't need to vacate the home, but expect noise, dust, and limited water access during work hours. The city inspection adds 1–2 days to the overall timeline.
